摘要 针对实时协同CAD系统的迟加入问题,提出了一种带容错机制的三多播组结构分布式"迟加入"算法。分析了协同CAD系统中迟到者加入机理,并深入探讨了"迟加入"算法实现的各个关键问题。实例分析表明该算法能有效降低初始化延迟、网络负荷和应用程序负担,能有效解决迟到者快速赶上设计进程又不影响其他协同成员工作的问题。 A distributed late join algorithm with fault-tolerance based on three multicast group is proposed, which can effectively solve the problem of client's late join in collaborative CAD system. The mechanism of late join is analyzed and the key issues of late join algorithm are discussed in detail. The prototype shows that the late join algorithm reduces the initialization delay and network load. This can well settle the problem of joining an ongoing session without interrupting others' work for a late-coming participant.
